android textview not changing the text

Question

i got a textview which should changes the text after the intent (directorypicker) finish.that doesn't work. heres the code:

text = (TextView) findViewById(R.id.choose3);
        text.setText(globalconstant.path);

should change the text when the intent returns the path:

private void addListenerOnButton() {
        choose_button = (Button) findViewById(R.id.button1);
        choose_button.setEnabled(true);
        choose_button.setOnClickListener(new OnClickListener() {
            public void onClick(View arg0) {
                // DirectoryPicker.START_DIR = "/mnt/";
                Intent intent = new Intent(settings.this, DirectoryPicker.class);
                startActivityForResult(intent, DirectoryPicker.PICK_DIRECTORY);
                // text.setText(globalconstant.path);
                text = (TextView) findViewById(R.id.choose3);
                text.setText(globalconstant.path);
                ;

            }
        });

    }

whats wrong with it? please help me! Thank you very much

It would be better if you can present the complete code. What is the `DirectoryPicker` doing? — akaHuman, Sep 12 '12 at 19:12

Probably, you should change the text in onActivityResult

@user1620554 Sure, if you tell me what DirectoryPicker is. Unfortunately I'm not familiar with DirectoryPicker – Alexander Kulyakhtin Sep 12 '12 at 19:12
@user1620554 : `onActivityResult(...)` see this link http://developer.android.com/reference/android/app/Activity.html#onActivityResult(int, int, android.content.Intent) – Squonk Sep 12 '12 at 19:15
@user1620554 So, override onActivityResult, get Intent parameter and get a string from it and update your textview with that string – Alexander Kulyakhtin Sep 12 '12 at 19:39

First test if you code work, replace text.setText(globalconstant.path); with text.setText("Test message"); is this work or not.

Then you can add a Log.d("TestAfterStartAct", "Test Message") open the commandos line and run adb logcat for show the log from the phone. Try to note while is the code run, before/after/never after the new Activity is show?

Some times you can get error with no updates GUI parts if the edit not is do from a UI thread, call for you text.postInvalidate() for update the GUI for the textview.

I had the same problem. The issue for me was that onStart is called when after onActivityResult was called. In the onStart I was inflating the view which was creating a new textview, with the default values.

In my case I solved it by saving the values in the onActivityResult and then apply the values in the onStart function.
